Why do this problem?
This problem uses the letters of the alphabet to study the effects of transformations such as rotations and reflections. It requires learners to visualise and predict outcomes. It could help learners to acquire and practise the language of both symmetry and transformations such as vertical and horizontal reflections, and turning through $180^o$.Key questions
Will it look the same after you have rotated it through
$180^o$?
How will it look after you have flipped it sideways/from top
to bottom?
Why don't you try using a mirror to see if you are
right?
Do these letters have a horizontal/vertical line of
symmetry?
Possible extension
Learners could systematically go through the letters of the whole alphabet.Possible support
Suggest using a mirror or cutting out some letters and trying them.Translations. Interactivities. Investigations. Practical Activity. Reflections. Symmetry. Rotations. Visualising. Compound transformations. Tangram.
